Warmshell Board Adhesive

Warmshell Board Adhesive is a breathable, moisture-wicking adhesive for Warmshell insulation boards applied to porous backgrounds. With a high lime content, it has natural biocidal properties and works with the rest of the Warmshell system to help keep the wall dry. Careful choice of ingredients mean that our adhesive does not contain toxic or persistent biocides and has very low VOCs.

We've designed this product carefully so that it contains  99% lime and sand, while still providing enough stickyness. That means it is much safer from rot or fire compared to most polymer based adhesives. It also means it acts as an active moisture-wicking layer, making sure any moisture in your wall isn't trapped.

Warmshell Board Adhesive is not for use as a tile or stone adhesive, nor for application to waterproofed backgrounds. When applied for External Wall Insulation (EWI) then mechanical fixings should also be used to resist wind loads
